GA43 4-ch 750w Power Amplifiers with DSP

GH12

12" High Efficiency Coaxial Slim Array Element

This passive 12” coaxial array element features a compact stainless steel, weather resistant cabinet that benefits from K-array™ SAT® (Slim Array Technology).

Its cardioid dispersion pattern limits the loss of energy in unwanted directions. More units can be joined together to form a line array and scale up the system.

Designed for high performance outdoor/indoor applications both for fixed and moving installations for live events, auditoriums, transportation facilities, stadia, theme parks and big and clubs.

Suggested amplifiers GA43 and GA46.

Stainless Steel Design

GH12 is made out of Grade 430 stainless steel, an alloy that combines good formability and finish capabilities with an excellent resistance to pitting and corrosion. 

The high density and neutral sonic characteristics of this material make it a perfect choice for applications that require compact design, resistance to adverse conditions and high sound performance.

Slim Array Technology ®

Line array loudspeakers with SAT (Slim Array Technology) feature a hyper-cardioid dispersion pattern in the low-mid frequency range, in which conventional line array loudspeakers are practically omni-directional, contributing to better directivity and control.

Clarity in the low frequencies and extremely fast impulse response are the advantages of speakers with SAT. The combination of these two factors leads to a significantly better acoustic result compared to traditional line array systems, particularly in terms of sound definition and noise pollution outside of the designated audience area.

Additionally, the compact profile of the loudspeakers benefits the user due to its practicality when transporting it, the ease of assembly and in general, the minimalist arrangement that optimizes the use of space, time, and therefore, general costs. for the use of these systems.
